Why does my fan look different than the others?

I don’t recommend it but I did this:

Exhaust Fan removal in 15 mins (GF PRO)

Thanks @Brooklyn_pro for the shout out. Glad my work helped. In principle you did what I did. Only difference is that in case for some reason there was an issue with removing the fan later, I actually didn’t gut the stock fan. I bought a super cheap replacement that was the same physical size but didn’t have PWM control or speed sensing so it was only like $6. I gutted this one and retained the factory fan in a drawer if I ever needed it since it’s a more expensive fan to replace. For others, …

Also some people removed just the grid but left the exhaust fan.

I removed the fan also and machine is much quite but I use the air filter.
